Abstract

Introduction: The methodological quality (MQ) is a complex multidimensional concept that assesses multiple items as design, methodology and analysis. There are few tools to assess MQ of studies in the field of therapy and these are also partially validated. The aim of this study is to determine the intra and inter observer reliability of the MINCIR scale for assess MQ of therapy articles. Methods: Study of validation scales. Was calculate sample size considering confidence level of 95%, accuracy of 2 points and standard deviation of 4.95, which gives 21 articles, select by simple random probabilistic sampling with Stata 10.0. Was determined intra and inter observer reliability of the scale and each one of its domains using intraclass correlation coefficient (ICC). Results: The ICC for interobserver reliability was 0.9. The ICC observed for the domains one, two and three was 0.97, 0.88 and 0.64 respectively. The ICC observed for intraobserver reliability was 0.99. The ICC observed for the domains one, two and three were 1; 1 and 0.91 respectively. Conclusion: Interobserver and intraobserver reliability for the MINCIR scale to assess MQ of therapy articles were determined.
